[英]“You may need an appropriate loader to handle this file type” with Webpack and Babel
[英]Webpack rendering sass, babel and es2015 - You may need an appropriate loader to handle this file type
我想配置webpack來渲染es15,react和sass。
添加用於sass加載的代碼后,出現以下消息:
ERROR in ./src/app.jsx
Module parse failed: /home/giedrius/projects/react-redux/react-redux-seed/src/app.jsx Unexpected token (7:11)
You may need an appropriate loader to handle this file type.
| class App extends React.Component {
| render () {
| return <Header/>;
| }
| }
@ multi (webpack)-dev-server/client?http://localhost:8085 ./src/app.jsx
我的webpack配置看起來像這樣:
const path = require('path');
let webpack = require('webpack');
let ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: './src/app.jsx',
output: {
path: path.resolve(__dirname, 'public', 'js'),
filename: 'app.bundle.js'
},
resolve: {
extensions: ['.js', '.jsx']
},
module: {
loaders: [
{
test: /.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
options: { presets: ['es2015', 'react'] }
}
],
rules: [
{
test: /\.scss$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: ['css-loader', 'sass-loader']
})
}
]
},
plugins: [
new ExtractTextPlugin("public/css/styles.css"),
]
};
服務器正在啟動並顯示標題,因此不確定為什么出現此消息。 任何人都有類似的問題嗎?
添加的代碼是規則和插件數組。
任何幫助,將不勝感激
提前致謝
您同時擁有加載程序和規則,它們基本上是同一件事。 裝載程序已重命名為規則。 您應該只有其中之一。
檢查此以獲取更多信息: https : //webpack.js.org/guides/migrating/#module-loaders-is-now-module-rules
嘗試這個:
module: { rules: [{ test: /.jsx?$/, loader: 'babel-loader', exclude: /node_modules/, options: { presets: ['es2015', 'react'] } }, { test: /\\.scss$/, use: ExtractTextPlugin.extract({ fallback: 'style-loader', use: ['css-loader', 'sass-loader'] }) } ] }
